For those who have gone through such events in the past, what can one expect in terms of long-term impact...should we expect some premature component failures? Does anyone have any stats to share?
I have experience with a different kind of event that might be of interest to a wider audience.
When the fire suppression system went off in a site, we had a lot of instant harddrive failures. I don't have any numbers, but let's say 5-10% of all hdd:s in the room died more or less instantly. Supposedly this was because of the air pressure shock when the inert fire suppression gas was released and the vents weren't big enough to release the overpressurised air outside.
I did some research and there are forum posts etc about these kinds of events happening in other places.
So, takeaway from this was RAID is an uptime tool, not a substitute for backups, and also, get a qualified ventilation/fire supression systems engineer to inspect your sites from this aspect.
